Contributions to risk injury evaluation of human skin contact caused by welding technology in mechanical engineering a company
2017
Assembly by welding is a very important pollutant technological process, mainly of the atmosphere and soil. The formation of gas in welding process is the result of electrodes, fluxes burning, formation of fused bath and welded seam. A large number of human operators feels different adverse effects on health. Most problems appears in respiratory system and include bronchitis, respiratory irritation, fever caused by smoke, changes in lung function, decreased immunity to infection and a possible increase of lung cancer risk. Very little information are available about effects on the organism and skin after exposure to fumes from welding, therefore. In this order, this paper do a risk assessme…
Direct visualization of pyrrole reactivity by confined oxidation in a Cyclodextrin Metal‐Organic Framework
2019
Metal-organic frameworks can be used as porous templates to exert control over polymerization reactions. Shown here are the possibilities offered by these crystalline, porous nanoreactors to capture highly‐reactive intermediates for a better understanding of the mechanism of polymerization reactions. By using a cyclodextrin framework the polymerization of pyrrole is restricted, capturing the formation of terpyrrole cationic intermediates. Single‐crystal X‐ray diffraction is used to provide definite information on the supramolecular interactions that induce the formation and stabilization of a conductive array of cationic complexes.
La publicidad actual: retos y oportunidades
2012
El entorno publicitario ha cambiado considerablemente en los últimos años: nuevos medios y herramientas, nuevos soportes, nuevos comportamientos de los consumidores, nuevas necesidades de los anunciantes… Estos y otros factores del macro entorno están obligando a los agentes implicados en el sector publicitario a emprender nuevos caminos y estrategias con las que alcanzar de forma más eficaz sus objetivos. Las agencias de publicidad en concreto han tenido que evolucionar considerablemente en los últimos años para poder satisfacer unas necesidades crecientes de sus clientes.

O conceito Cultura Tecnológica e um estudo no meio educacional
2009
Resumo: Neste artigo apresenta-se, inicialmente, um breve estudo acerca das evoluções sociais e da sua relação com a tecnologia. Em seguida, a partir do conceito de cultura, trata-se das variações culturais no âmbito tecnológico, buscando-se analisar a relação entre o homem e a tecnologia como um processo de socialização e de apropriação. Num segundo momento, são apresentados alguns resultados de um estudo de caso que acompanhou a criação, implantação e utilização do portal da Rede Municipal de Ensino de São Paulo. Dentre os objetivos deste estudo destaca-se o interesse por se compreender a percepção do educador acerca desse espaço. Confirmando a hipótese inicial, percebeu-se que a utilizaç…

Employee opportunities for self-directed learning at technology organisations : features and frames of self-directed learning projects
2020
The importance of self-directed learning (SDL) in a business environment has been highlighted as a way to increase an organisation’s competitiveness and innovativeness. While organisations increasingly require SDL from employees, less attention is paid to the situations and frames enabling it. This study examines self-directed learning projects (SDLPs), situations in which SDL is realised as an individual or collective phenomenon. Based on ethnographic research, this study’s data consisted of field notes, field records and interviews. I used analysis of key incidents and ethnographic content analysis as an analytical tools. Four types of SDLPs was identified in the organisations studied: or…
Professional identity in relation to vocational teachers’ work : an identity-centred approach to professional development
2018
This paper reports a study on teachers’ professional identity and work in vocational education. The findings showed that vocational teachers’ work included vocational teaching within the school, developmental work, technology-enhanced work, professional duties outside the school, and educational duties within the school. Furthermore, the study revealed the harmonious and tensioned relationships between these elements of the work and teachers’ identities. Recognition of the nuanced nature of these relationships provides a perspective for promoting teachers’ professional development. From a practical perspective, there is a need to support vocational teachers’ identity work and the adoption o…
TEL@work: Toward integration of theory and practice
2014
This paper examines technology-enhanced learning at work in the context of the integrative pedagogy model. The basic idea behind this model is to create learning environments whereby the four basic elements of professional expertise (ie, theoretical, practical, self-regulative and sociocultural knowledge) can be integrated. The paper illustrates two basic ways of applying the model in technology-enhanced learning at work. First, examples of how to make use of existing technologies, especially social media, to empower learning at work is presented, and second, an instance of the way the model is used in the design of specific technologies for enhancing collaborative learning in the work cont…
Teacher beliefs on the significance of technology in education : the influence for inclusion in the andalusian teaching centers
2014
Este trabajo muestra resultados parciales de un Proyecto I+D de Ministerio de Ciencia y Tecnología español sobre centros TICs andaluces y sus repercusiones en los procesos de enseñanza-aprendizaje. Nos planteamos mediante encuesta indagar en las creencias del profesorado sobre la tecnología en la educación, su influencia en los procesos de aula. Los datos obtenidos nos aportan indicios que nos aproximan a la hipótesis inicial, confirmando parcialmente que las creencias que el profesorado tiene sobre el significado de las tecnologías en la educación se encuentran relacionadas con su frecuencia y uso, sus percepciones sobre la integración organizativa y curricular, y con su formación y capaci…
ICT competences in university students in the field of education and its relationship with learning strategies
2016
Este estudio se enmarca en el contexto universitario, y concretamente en los estudiantes, ya que son los actores principales de su proceso de aprendizaje. El objetivo se centra en analizar las competencias en TIC (tecnológicas, pedagógicas y éticas) de estudiantes universitarios del ámbito de la Educación y su relación con las Estrategias de Aprendizaje. Además, se tienen en cuenta en el planteamiento desarrollado determinadas variables personales y contextuales claves. La población de referencia la constituyen los estudiantes universitarios de titulaciones pertenecientes al ámbito de la Educación de la Universidad de Valencia. La información se ha recogido a través de cuestionarios. Se ha …
